These modules +can be installed using ``pip3`` (the Python Package Installer). Passing this +requirements file as an argument to ``pip3`` automatically installs the specific +module versions required by |TF-A|. + +An example set of installation commands for Ubuntu 18.04 LTS follows, assuming +that the working directory is ``docs``: + +.. code:: shell + + sudo apt install python3 python3-pip plantuml + pip3 install [--user] -r requirements.txt + +.. note:: + Several other modules will be installed as dependencies. Please review + the list to ensure that there will be no conflicts with other modules already + installed in your environment. + +Passing the optional ``--user`` argument to ``pip3`` will install the Python +packages only for the current user. Omitting this argument will attempt to +install the packages globally and this will likely require the command to be run +as root or using ``sudo``. + +.. note:: + More advanced usage instructions for *pip* are beyond the scope of this + document but you can refer to the `pip homepage`_ for detailed guides. + +Building rendered documentation +------------------------------- + +From the ``docs`` directory of the project, run the following commands. It is +important to note that you will not get the correct result if the commands are +run from the project root directory, as that would invoke the top-level Makefile +for |TF-A| itself. + +.. code:: shell + + make clean + make html + +Output from the build process will be placed in: + +:: + + /docs/build/html/ + +-------------- + +*Copyright (c) 2019, Arm Limited.
